摘要： A gasket clamped between two members fastened by a fixture, includes first and second metal plates laminated together to form the gasket, fixture holes formed in the first and second metal plates for inserting the fixture therein, sealing subject holes formed in the first and second metal plates, fastening-stress concentration areas located on the first and second metal plates between the fixture holes and the sealing subject holes where a fastening stress concentrates when the two members are fastened by the fixture, and a linear bead formed on the first metal plate only at the fastening-stress concentration area to reduce the fastening stress when the two members are fastened. The linear bead projects to a side opposite to the second metal plate, and is disposed on an axis line connecting a center of the fixture hole and a center of the sealing subject hole in the first metal plate.

摘要： A cylinder head gasket is formed of a metal plate, a sealing bead formed in the metal plate around a liquid hole, and a peripheral bead formed in the metal plate to extend around a periphery of the metal plate. At least a part of the peripheral bead is set to have a surface pressure lower than that of the sealing bead when the gasket is tightened by that the height of the peripheral bead is lower than that of the sealing bead or the width of the peripheral bead is greater than that of the sealing bead. Thus, when the gasket is tightened, substantially uniform and optimum load share can be obtained on the peripheral bead and the sealing bead for the fluid hole.

摘要： A cylinder head gasket of the invention is used for an internal combustion engine with at least three cylinder bores. The gasket is formed of a metal plate extending substantially throughout an entire area to be sealed, and a reinforce coating. The metal plate includes two end holes, at least one inner hole sandwiched between the two end holes, and beads surrounding the respective holes. The two end holes and at least one inner hole are arranged linearly to correspond to the cylinder bores of the engine. The reinforce coating is deposited around the peripheral portion of the at least one inner hole so that sealing pressures are formed substantially equally around the two end holes and at least one inner hole. Other reinforce coatings may be deposited around the peripheral portions of the end holes.

摘要： A cylinder head gasket for an internal combustion engine is formed of a first metal plate and a second metal plate laminated together. The first and second metal plates have first and second beads laterally spaced apart from each other and facing each other. A resin layer is deposited on the first metal plate to extend continuously from an inner portion to an outer portion relative to the first bead such that the second bead is disposed on the resin layer. The resin layer securely seals between the first and second metal plates while providing compressibility.

摘要： A cylinder head gasket includes two or more metal plates laminated together to form the cylinder head gasket, a plurality of cylinder bores formed in the metal plates, a plurality of annular seal portions, each surrounding each the plurality of cylinder bores to seal therearound; a plurality of bolt holes disposed at an outer peripheral side of the plurality of annular seal portions so that fastening bolts are inserted therethrough, and a partition protector having a thermal deformation coping portion, located in the two or more metal plates between two of the bolt holes. The thermal deformation coping portion includes offset slits in each metal plate such that none of the slits are aligned in a lamination direction of the thermal deformation coping portion. The slits prevent damage to the cylinder head gasket due to temperature fluctuations by accommodating thermal expansion or contraction of the cylinder head gasket.

摘要： A gasket formed by laminating two or more metal plates includes a seal target hole, an annular seal portion sealing an outer peripheral edge of the seal target hole, and a plurality of bolt holes disposed at the outer peripheral side of the seal portion. Each metal plate constituting a thermal deformation coping portion is provided with slits intersecting in a longitudinal direction of the metal plate and each slit constitutes a lamination portion of the metal plate so as not to penetrate in a lamination direction. When one seal target hole is provided, a portion suspended in the seal target hole is formed at the thermal deformation coping portion, and when multiple seal target holes are provided, at least one of portions interposed between the adjacent seal portions and a portion interposed between the adjacent bolt holes is formed at the thermal deformation coping portion.
